Vulnerability Information

Severity: High
Vulnerability Published: 2014-03-01
Patch Published: 2014-03-01
CVE [?]: CVE-2014-0050, CVE-2014-0094
CPE [?]: cpe:/a:apache:struts

Synopsis

A web application running on the remote host uses a Java framework that is affected by multiple vulnerabilities.

Description

The version of Apache Struts running on the remote host is 2.x prior to 2.3.16.2. It, therefore, is affected by multiple vulnerabilities:

- A denial of service vulnerability exists in MultipartStrea.java in Apache Commons FileUpload due to failure to handle exceptional conditions. A remote, unauthenticated attacker can exploit this issue to cause the application to enter an infinite loop which may cause a denial of service condition. (CVE-2014-0050)

- A class loader manipulation flaw exists in ParameterInterceptor due to improper validation of input data. An attacker can exploit this issue to bypass certain security restriction and manipulate the ClassLoader. (CVE-2015-0094)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache Struts version 2.3.16.2 or later
